Abstract: Coating layers made of pyrocarbon prevent the release of radioactive fission products from HTR fuel kernels. According to the present state of the art, coating of these fuel kernels is effected exclusively in fluidized-bed reactors. Due to the requirement of economic efficiency, an air-cooled fluidized-bed coating facility featuring an increased daily throughput, capable of processing the nuclear fuel produced during refabrication in the HTR fuel cycle, is presented in this study. Aprerequisite for this improved throughput is an increase of the heavy-metal fraction to 2 kg per charge and a dimensioning of the fluidized bed to 200 mm diameter. Furthermore, a quasi-continuous operation is achieved by loading and unloading the coater at high temperatures. For the necessary new conception of such a coating facility, the individual components are calculated and designed and the overall facility tried in coating operation.
